One big problem with salvage-yard 14-bolts and 60s is that most of them served under work trucks and were severely thrashed before they were retired. However, Boyce Equipment sells primo used and rebuilt 60s and 14-bolts from government surplus. And Dynatrac offers all-new Dana 60s (44s and 70s too) in high-pinion or standard versions. All Dynatrac 60s (as shown here) are fitted with new 35-spline, 1 1/2-inch axleshafts and feature Dana-70-spec spindles, wheel bearings, and wheel hubs. They can be fitted with disc brakes as shown and five-, six-, or eight-lug patterns. Dynatrac axles carry a 12-month warranty.
